Stratix 2000 Ethernet Unmanaged Switches
Broadcast Storm ProtectionA broadcast storm occurs when a network is overwhelmed by continuous multicast or broadcast traffic typically caused by loops in the network. A severe broadcast storm can block all other network traffic. Stratix® 2000 switches provide protection against broadcast storms. When the broadcast storm protection feature is enabled, the switch drops incoming broadcast traffic if the traffic exceeds a certain threshold.
Stratix 2000 switches use two methods to determine the threshold for incoming broadcast traffic, depending on the switch catalog number:
• Packet-based threshold—The switch counts the number of broadcast packets received within a time cycle. Once the number of broadcast packets reaches the maximum number of packets in the time cycle, the port drops any excess broadcast packets. For threshold values based on packet number, see Table 1.
• Rate-based threshold—The switch tracks the bandwidth of each port based on a maximum bit rate. Once a port reaches the maximum bit rate, the port drops any excess broadcast packets. For threshold values based on rate, see Table 2.
You can enable or disable broadcast storm protection by using DIP switch SW1 on the top panel of the switch:
• To enable the feature, set SW1 to the On position and restart the switch. • To disable the feature, set SW1 to the Off position. By default, the feature is disabled.

DIP SwitchesThere are two DIP switches on the top panel of the switches. Each switch has On and Off states.
The function of the DIP switches varies by catalog number.
Status IndicatorsThe status indicators on the switches indicate the following:
• Status of each power supply• Status of port speed• Status of network connection or activity
The function of the status indicators varies by catalog number:
• 5- and 8-port Fast Ethernet Switches on page 5• 10-port Fast Ethernet Switches on page 6• 16- and 18-port Fast Ethernet Switches on page 7• 5- and 10-port Gigabit Ethernet Switches on page 8
